- Glass: wash the screen and wipe the rubber edges. Wax, silicone sprays and some rain repellents make blades grab and skip.
- Rubber: hardened or cracked rubber chatters even on clean glass. Replace the blades.
- Connector: a blade that moves on the arm, often with a poorly fitting universal adapter, rocks as it changes direction. Refit it or use a blade with the right connector.
- Arm angle: if the blade does not stand square to the glass, it drags on one edge and judders.
How to check the arm angle
Remove the blade and lower the arm gently onto the glass, protecting the screen with a cloth. The flat end of the arm should sit flush with the glass. If it is visibly tilted, the arm has twisted. Some owners straighten it with a small spanner and padding; if you are not comfortable doing that, a garage or dealer can reset it.
Land Rover has published a technical bulletin that puts poor wiping, noise and judder down to the wrong angle of attack of the blade on the glass, and also mentions worn arm mountings and spindles.
Squeak only on a dry screen
A squeak when you flick the wipers over dry glass is normal friction. If they squeak or judder on a wet screen too, work through the list above.

Frequently asked questions
Will new blades fix juddering?
If the rubber was hardened, yes. If the arm is twisted or the glass is waxed, new blades will judder too, so check those first.
Can rain repellent cause judder?
Some can, especially on older blades. If the judder started after applying one, clean it off the wiped area and see if it stops.
Why does only one wiper judder?
Each arm can twist on its own, and the driver's blade is often longer and works harder. Check that arm's angle and that blade's connector.
